FWIW, no leaky head gasket and It's been run up to 240 a FEW times since the 192k rebuild, and even pegged 260 and a "ding" twice. These engines are a little tougher than everyone makes them out to be.

I'm going to slap the stock intake back on there tonight, and go find a paper filter.

I am using an Autozone TPS, which was all that was available when I needed to replace it 18 months or so ago.

When I bought my Jeep, I had two codes, one for a MAP sensor, and one for the number 7 injector/misfire. That's why I found this site. I did a search for my codes on google and found that the P0307 was often a misread and just the TPS. I replaced both the TPS and MAP sensor with Mopar sensor (because of the advice of this forum) and the codes have been gone for 12 months.

As far as my engine temp goes, it got a little warm again today. Not as hot as before but it went up to about 215, which it never did before my overheating issues. I'm not worried about it, not until it hit 225 or 230 again, but it does appear that the temp sending switch helped. I guess I never really had a problem in the first place. I always chase problems backwards. I start with the hardest and most expensive part and work my way backwards, until I finally change the simplest and least expensive part and then... whala, it's fixed!!

Well, if you'll jump back a few pages, I've had P0300/P0302/P0307 pop up a few times. After this recent pop up, I changed the coil packs on 2 and 7, and then last night P0307 popped back up. My boss has a Ram 1500 with the same engine, and after changing the coil pack, and a whole new set of plugs, P0307 kept coming back. What we ended up doing was replacing the injectors for all the cylinders. For his, the replacement injector has 4 holes instead of 2, so after buying one, he decided to buy all new ones. He hasn't had the problem since. For the Grands, it's 2-hole until 2003, when they switched to 4 hole, but the H.O. engine has the 4 hole injectors in 2002 as well.

I'm not sure how I need to proceed. I'm going to swap back to the factory intake tonight (when it cools down, GD it's hot out there). I need to get a paper filter for it. Anybody want to buy a K&N?

Yeah, I knew that you were getting multiple codes, that's why I was wondering if it was just the P0307, but with your experience with the injectors on the Dodge, I'm not sure either... Good luck man.

I just installed a K&N CAI a few months ago, looks like I'm putting my stock airbox back on as well. I might try to pipe the resonator out of the equation though, just run a pipe to the stock airbox. Any ideas?

I had a long post typed out earlier, but a massive storm+tornado coming through the area diverted my attention and my backup batteries died on all the network equipment at the house.

It lifted my 80 lb gas grill off the ground and threw it at my building, which ripped my metal storage building right off the base, and tossed it over the hill. 500k people without electric (almost 1/3 of the states population). Somehow my mother in law right up the road has power, so the wife and kids are there. I took my parents propane powered cooking gear, and some food staples, and now I'm back at the house to hold down the fort against any looting.

Did NOT get the intake swapped back over. Rofl
